Vetted Performance Status

Grand Challenges Canada (GCC) developed a case study on a twelve-month project where 300 cookstoves were deployed. GCC stated the key findings on Jiko Raha’s performance as:

  • Out of the 300 households studied, 200 households (66%) continuously boiled the water using the Jiko Kenya stove every day, which exceeded the initial target of 60%.
  • 95% of households reported an 80% reduction in the incidence of waterborne diseases, compared to the period before they used the stove.
  • In Kitui County, the percentage of children who missed school as a result of water-related illnesses was reduced by more than 80%, due to the project.
Global Innovation Exchange on their database about the Jiko Raha stated that "the stove through pilot studies was able to save a household USD 17.85 monthly with fuel reduction from USD 23.81 to only USD 5.96 monthly a 75% reduction in fuel costs and zero cost in water sanitization which has contributed to reduction of water-borne diseases."


The safety concerns associated with the usage of wood-burning cookstoves are primarily related with carbon dioxide, carbon monoxide and sulfur dioxide emissions. Another significant safety concern is domestic accidents such as accidental burning or spill-overs.
